Murmur

This one runs as an actual chatbot talking to a local AI on your own machine, not a scripted visual novel dressed up to look smart. Two girls exist so far, and their artwork shifts as the conversation moves forward.

You start by picking a base personality for the girl who lives with you, good girl, tsundere, kuudere, or broken, then reshape her further through a fully customizable persona. The other girl, met on a cruise ship, runs on her own thread. Context sticks around far longer than a typical online chat, with an auto-compact system keeping the story from falling apart once the message count climbs.

Underneath that, bots react differently depending on how you've actually treated them, and a seed system nudges in small variability each time you clear the log, so rest
